Q: Carnivorous plants of northern Africa--little known species!
A:
The number of carnivorous plant species known from Africa, Madagascar, and the Seychelles is huge, so to make this page a
little less overwhelming I have excluded those carnivorous plants that are found exclusively in the three
countries at the southern tip of the continent: South Africa, Lesotho, and Swaziland.
Even so, I am afraid that the carnivorous plant biodiversity of Africa is so great that my attempts to make the page more
tractable are defeated! Most of Africa's carnivorous plants are in the genera
Drosera, Genlisea, and Utricularia. Many
of these species are very poorly known.
Smaller genera
The African inventory includes noteworthy but small additions from five other genera:
- Aldrovanda vesiculosa in Botswana (and possibly Zambia and Mozambique).
- Drosophyllum lusitanicum in Morocco.
- Nepenthes madagascariensis and N. masoalensis from Madagascar; Nepenthes pervillei from the Seychelles.
- Pinguicula lusitanica and P. vulgaris in Morocco. The Moroccan species "P. fontiqueriana" is likely P. vulgaris or P. grandiflora.
- Triphyophyllum peltatum in Sierra Leone, Libera, and Cote d'Ivoire.
Without false humility I admit that I think the best treatment of the carnivorous plants of this region is in one of my own papers
that I wrote for the Italian Carnivorous Plant Society (Rice 2008b); I temper my prideful admission by sheepishly noting I
accidentally excluded Utricularia simulans from that treatment. Oops.
